Topmetry Plastic Injection Molding Services

From high-performance prototypes to durable production-grade components, Topmetry delivers tailored injection molding solutions with advanced tooling, overmolding, and insert molding.
Plastic Injection Mold Tooling
Plastic Injection Mold Tooling
Achieve precision and repeatability with high-performance aluminum or steel molds tailored to your design. We offer tight tolerances, optimized mold flow, and rapid lead times—perfect for both prototyping and full-scale production."
Overmolding
Overmolding
Create multi-material, multi-color parts with enhanced performance and aesthetics. Topmetry’s overmolding process bonds a soft or rigid plastic layer over an existing substrate, delivering improved grip, sealing, and ergonomics for both consumer and industrial applications."
Insert Molding
Insert Molding
Seamlessly combine metal and plastic in a single molding cycle. Our insert molding process securely embeds threaded inserts, pins, or other components into engineering-grade plastics—improving part strength, and reducing assembly time."
